摘要:
Disclosed is a process which comprises reacting a polymer of the general formula ##STR1## or ##STR2## wherein x is an integer of 0 or 1, A is one of several specified groups, such as ##STR3## B is one of several specified groups, such as or mixtures thereof, and n is an integer representing the number of repeating monomer units, with a halomethylethyl ether, a hydrohalic acid, and acetic acid in the presence of a halogen-containing Lewis acid catalyst, thereby forming a halomethylated polymer.
